2020 Globe at Night Campaigns

Globe at Night has been collecting data about the night sky since 2006. All of that data is available to download in a variety of formats, and also can be explored in our interactive map. Links to previous years’ data is available below. We are just getting started with this year’s campaign, but you can explore the data from 2020 as it comes in.

Globe at Night - Sky Brightness Monitoring Network (GaN-MN)

The GaN-MN project, an extension of the original Globe at Night project, is a global night sky brightness monitoring network using a commercially available meter (SQM-LE by Unihedron) for long-term monitoring of the light pollution conditions in different places around the world.
